2) Find the cost of 8 kg of rice, if the cost of 10 kg is Rs 325.
3) in an orchard, there are 128 mango trees in 8 rows. If all the rows have an equa
number of trees, how many trees would there be in 13 rows?​

Answer 1

Answer:

1) Given : 20 metres of cloth cost ₹3600

To Find: Find the cost of 16 metre of cloth

Solution:

Cost of 20 meters cloth = ₹3600

Cost of 1 meter cloth = \frac {3600}{20}

20

3600

So, cost of 16 meter cloth = \frac {3600}{20}\times 16

20

3600

×16

= 2880

Hence the cost of 16 meter cloth is Rs.2880

2) 8 kg→ Rs. 325 using unitary method

1kg →325/8

10kg→ 325/8 × 10

= Rs. 406.25

3) 8 rows..... 128 trees

1 row..... 128/8 trees = 16 trees

therefore: 13 rows..... = 16 × 13 trees

= 208 trees
